With conventional gain controls, changes are made for new echoes only when a change in the gain setting is applied. With the FCV627’s Post-Processing Gain Control, changes in the gain setting are applied to new echoes as well as all of the echoes already on the screen. Because the changes are applied to both new and existing returns, you will be able to quickly and easily find the right gain setting for your conditions.

Bottom Discrimination Mode:

The FCV627’s Bottom Discrimination feature indicates if the bottom is composed primarily of rocks, sand, gravel or mud, providing valuable information to help you locate rich fishing grounds and boost your catch of the day.

Accu-Fish:

Accu-Fish allows the FCV627 to display the actual fish size on the individual fish echo on-screen. When used concurrently with Fish Marks, Accu-Fish is a great help in identifying fish targets on the display. Alternatively, Accu-Fish can display the actual depth of the fish target instead of fish size.

Furuno Digital Filter:

You’ve probably heard about digital fish finders, but aren’t quite sure what the difference is. The main difference is the filtering capabilities and auto adjustments. FDF (Furuno Digital Filter) technology helps adjust gain, STC “Clutter” and output power, as well as suppress main bang (the echoes just below the transducer.) It also makes the picture clearer and easier to decipher. But even the best digital filter won’t help unless you start with a solid basis, such as Furuno’s renowned fish finder technology.

The FCV627's waterproof construction allows it to be installed on any bridge. Audio and visual alarms alert you whenever preset limits are met for water depth, water temperature and fish echoes. Selectable display modes include High or Low Frequency, Dual Frequency, Zoom, Nav Data, A-Scope, Marker Zoom, Bottom Zoom or Bottom-Lock. Furuno's TLL (Target Lat/Lon) output allows you to interface the FCV627 with your Furuno chart plotter so you can mark any spot you desire and save it as a waypoint, enabling you to return to it whenever you desire.
